Hi. I've bought this exhaust can and like an idiot I thought that it wouldn't be stupidly loud, I put it on my bike and it sounded like a machine gun at just 2k revs and I didn't dare drive anywhere. I was going to try and return it but before I do I'd like to see if there's anything that can be done to quiet it down to less silly (and legal) levels. I've seen these db killers on eBay and Amazon, are they very effective or not? Are there any options aswell?
